Ziwipeak Deer Shank Bone Full

Can my dog eat the whole bone and not just the outside? Do I need to rehydrate it?

Does this bone come in a protective (plastic) wrap? Doesn't look like it on the pictures?

Does this need to be refrigerated or frozen if not eaten right away or after the package is opened or the dog has chewed it some?

Does the beef esophagus include the thyroids?
